Be it known that l, ALLEN A. VAN OnsnALii, a citizen of the United States, residingat Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invei'ited new and useful Improvements in Vibratory Lubricators, of which the following is a specification.

This invention relates to lubricators or auton'iatic oilers and it has more particular reference to devices of the kind in `which the emission or discharge of the lubricant is automatically controlled consequential upon the vibrations surroundingand eomniunicated directly to. said lubricator. More especially this invention relates to automatic lubricators which are characterized by a spring influenced discharge valve and it has for its primary object the provision of an improved type of controlled and regulatable lubricator for use upon machines or moving partstlieieof which are susceptible to coii stantand varying vibrating disturbance..

Another object o f this invention is to provide an automatic vibiatory actuated lubricator of novel structure that is so adapted when desired to make easy the successful cleansing of the bearing or other part on which it is mounted without emptying, disturbing any of the contents, or removing said lubricator.

A furtherobject of this invention is the provision of a highly sensitive vibratory lubricator that is easily regulatable to automatically meet requisite needs and when so required.-

A still further object is to provide a novell form of vibratory lubricator which will automatically operate with equal successwith an oil of low viscosity as with' an oil having a higher viscosity.

Still further this invention has for objects theI provision of a vibratoiy lubricator coniprisiiig but few and easily manufactured parts that can be readily assembled and ad-y justed, and which is socoiistructed that dirty or grit cannot impair oriaifect its successful operation in that the valve proper and its seat are so fashioned that it is impossible for the latter` to hold or permit the adherence thereto of any matter which might prevent said valve from properly seating whereby loss or draiiiiiigaway of the lubi'i-. cant or flooding of the bearing or other part ure l of a. slightly toy which. the device may tively prevented. I V"lViththe foregoing and other objects in view as willbecome' clearly apparent from the following description this invention consists primarily in providing a vibratory lu bricator the upwardly seatingl valve whereof is formed with a hollow adjustable stem, n'ieaiis being associated therewith whereby the bore thereof vcan be movedfinto direct registering axial alignment with the i discharge ductk when desired. The invention also further consists inv certain novel 'features of construction, combinations and arrangements of lparts hereinafter fully described and more specifically defined by the be applied is evecappended claims. y 1 ln the furtlierdisclosure of tlieinvention reference is to be had to the accompanying sheet of explanatory drawings constituting a part of this specification, and in which like characters of reference designatel the same or corresponding parts in all the views.

Figure Gis a similar sectional View to Figveiition; and,

' Figure 7 is illustrative of the application oil-this invention to a shackle bolt.

' Referring more particularly to the views the oil cup or body portion proper of my iinproved vibratory lubiicator is designatedby the,` numeral S and said body portion is formed with a fuiinelsliap`ed bottoni; 9 adapted to seat leak-proof between yan inner similarly vshaped bottom 10 and the correspondingly flared upper inner part l1v of the hexagonal. connecting member 12 which is iiiodied form of the inexternally screw-threaded at 13 for in'ser` d tion into the bearing or lpart to be lubricated.

,v downwardly rolled catch 19 adapted fory snapping or gripping (3o-operation with the beaded part 2O provided for the purpose diametrically opposite to the aforesaid hasp 18 on tliecup lor body 8.

The valve seatconsists of a tubular nipple i 2-1 seated frictionally ltight in the bore 22 of the aforesaid shank 14 and it is formed vwith an upwardly flared part or seating shoulder 23, whilst its top face 24C is finished off square with the longitudinal axis of its bore 25 and is of a diameter to register with the lubricant discharge duct 26. Upwardly seating on the flared part or valve seat proper 23 is the corresponding flared inner end`2rof the lowei or valve section 28 of an eXteriorly screw-threaded tubular stem 29, said stein 29 being threaded into the section 28 after the tubular nipple 2l has been firmly secured in the bore 22. In

` ordertorprovide an eiiicient means for normally seating the valve sectiony 28 on itsv seat 23 there is interposed between the inner concave part 30 of the inner bottom 10 and a nut or threaded collar 31 on the tubular stem, 29 a compression spring 32, it being i perfectly obvious that this spring' functions to hold thevalve section 28 on its seat 23 and that by manipulatingthe nut or collar 31`up or down the stem 29 its sensitivity may .be varied or accurately adjusted to desired requirements. Cross cuts or radial grooves 33 may `be provided in the nut or collar 3l whereby it can be moreA easily nia-,

nipulated.

In the modified form of the invention shown by Figure 6l itwill be seen that the valve section 28 is considerably extended, and' that the spring 32 is housed therein being interposed between a shoulder 34 on the upper end of the tubular nipple 21 and a corresponding shoulder 35 at the inner end of the tubular screw-threaded insert 3G at its yupper end. ln this instance the adjustment of the spring 32 is effected by i screwing the tubular insert 36 inwards or outwards relative to the vvalve section 28 as will be perfectly obvious. y

In Figure 7 I have illustrated, the applicability of my improved vibratory lubricator to a shackle bolt 37- and it is here .most particularly emphasized that tions and sizes of the various parts in Figures 1to 6'inclusive,l have been Ydrawn .three the proporn to four times their actual size in order to clearly illustrate their respective relation and for a clearei' comprehension of their functioning. v

Briefly described the operation of the iinproved vibratory lubricator is as follows: Assuming that the lubricator has been filled with oil as shown in Figures l and 6 it will be self-evident that when there is no surrounding or communicated vibrations or joltings the tubular stem 29 and connected valve section 28 will remain vertically poised as Shown by Figure 1 with the said valve section in close engagement on its seat 23 thereby preventing the discharge of the oil therethrough and to the discharge duct 26. On the other hand whenever vibration is communicated to the lubricator it will be clear that the tubular stem 29 and connected valve section 28 will be rocked to a greater orA lesser degree according to the intensity of said vibrations which will result in the unseating` of the valve section 28 as shownI iii-Figure t whereupon the oil will percolate oi'vflow through the flared inlet 38, and enter the bore 25 of the nipple 21 in sufiicieiit quantity-to lubricate the bearing or other partv on which the device is installed. Gbviousl)7 according to the sensitivity ofthe spring 32 or its degree of regulation, the tubular stein will rock more or less rapidly whereby the lubricant fed through the discharge duct 26 can be controlled desired, and it, will be apparent that when the vibrations cease tlie valve section 28 will be automatically reseated under the action or recoil of said spring 32. Still further it is to be observed that by removing the lippedl cover 16 and pressing down on the head of the tubular stein 29 the valve section can be seated on the heifeinbefoie referred yto' concave part 30 as shown by Figure 5 thereby effectively cutting off any tendency for the lubricant to fiow out of the lubricator whereupon a suitable cleaning` fiuid or oil can be forceddown the bore 35 of'said stein and through the discharge duct 26 for flushing or thoroughly cleansing the moving part without in yany. way disturbing the contents ofvr the lubricator. Another advantage accruing to my novel construction of vibratory lubricator is the fact that whenever there is an excess of, lubricant or oil iii a bearing or other moving `part on which the deviceis used and a back pressure is caused for some unforeseen reason the surplus oil or lubricant will be forced .back up through.

the duct26 and nipple 21 past the valve 28 and returned into the oil cup or body 8, from wlience'it canbe re-discharged again as liereinbefore set forth... Still further it is to be remarked that by lthe peculiar ar-y rangement and disposition of the severall parts the pressure above the lubricant level in the cup or body I8 will be the same as.

lOl)

that of the bearing or other moving part supplied therefrom, whilst when the vibratory lubricator comes to rest there will be a slight lag of lubricant that will be fed into the bearing or other moving part after said part ceases motion which will ensure ease in restarting.

By reason of tubular nipple 2l, which projects' upwardly from the bottoni of the oil reservoir, dirt and sediment in the oil are prevented from lodging on the valve vseat and interfering with the valve action, such dirt settling to the bottom of the cup below the level of the valve.

From the foregoing it will be clearly apparent that by my invention there is provided an exceedingly simple and efficient vibratory lubricator for use on machinery and moving parts subject to constant and variable degrees of vibration," and whilst there has been shown and described the best form thereof at present known to methe same is not to be construed as conclusive, as it will be self-evident that many detail changes or variations may be effected without departing from the true spirit and intent of the invention, therefore, the right is hereby reserved to make such changes and other modifications 'as fairly lie within the sco e of the appended claims.
